\title{ Data on Response Times for Scizophrenics and non-Schizophrenics   }
\description{
   Response times (in milliseconds) for 11 non-schizophrenic and 6 schizophrenic
   individuals.  
}
\usage{data(schiz)}
\format{
  The format is:
 num [1:30, 1:17] 312 272 350 286 268 328 298 356 292 308 ...
 - attr(*, "dimnames")=List of 2
  ..$ : NULL
  ..$ : chr [1:17] "nonsch1" "nonsch2" "nonsch3" "nonsch4" ...

  A numerical matrix with individuals as columns.
